'The Vampire Diaries: The Complete Fourth Season'

A major change takes effect in this round of the CW series, with heroine Elena (Nina Dobrev) transitioning from human to vampire ... immediately changing the nature of her relationships with already undead brothers Stefan and Damon (Paul Wesley, Ian Somerhalder).

One episode of this season of the show doubles as the pilot for the fall spinoff series "The Originals." DVD extras: six "making-of" documentaries; deleted scenes; outtakes; fan video; fan artwork. *** (Not rated: AS, P, V) (Also on Blu-ray)
